ZF and Porsche have developed a modular hybrid transmission kit.
With an 8-speed dual clutch transmission (8DT) as a basis, ZF and Porsche have collaborated to develop a modular hybrid transmission kit for sports vehicles, catering for current and future drive trends.
The sports transmission, for rear-wheel and all-wheel drives, distinguishes itself with its rapid shift times. One major development was to make electric power an option: thanks to a new gear set design, it was possible to integrate a 100kW hybrid module without increasing the length of the transmission, as compared to the current 7DT sports transmission.
Another goal was an integrated all-wheel distribution option, driving the front axle using a hang-on clutch. Power loss in the basic transmission is reduced by up to 28% due to several factors: the gear spread, which at 11.17 is very high, an additional eighth gear, a demand-driven lubrication system and an electronic
transmission control unit (TCU) specially developed and produced independently by the company.
